The Net Of A Square Pyramid And Its Dimensions Are Shown In The Diagram. What Is The Total Surface Area

Answers

Answer 1

Answer:

c

Step-by-step explanation:

Answer 2

The surface area of the square pyramid is 1040 ft² in the given figure.

What is the total surface area of the pyramid?

The total surface area of the given pyramid can be expressed as:

Surface area of a square pyramid = A + (1/2) p × s

where A is the base area, p is the perimeter of the base, and s is the slant height

As per the question, we have

length (l) = 20 ft

base perimeter (p) = 4l = 4 × 20 = 80 ft

base area (A) = l² = 20² = 400 ft²

slant height (s) = 16 ft

Substitute the values in the formula for surface area:

Surface area = 400 + 1/2 × 80 × 16

Surface area = 400 + 1280/2

Surface area = 400 + 640

Surface area = 1040 ft²

Thus, the surface area of the square pyramid is 1040 ft².

Which of the angles in the figure are supplementary to Ð5?

Answers

Answer:

Option C) Angle 6 and 7 only

Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

So here the angle supplementary to Angle 5 would be 6, since adding both would get us 180 degrees. Then there's angle 7 which would also give us 180 degrees when added to angle 5.

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. (5 points)

−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25
Step 2: −5x = 53
Step 3: = -5x/-5=53/-5
Step 4: x = -53/5

Answers

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25        WRONG

- 5x - 25 = 78

- 5x - 25 + 25 = 78 + 25

- 5x                  = 103

x = - 103/5

x = - 20,6

Answer:

Step-by-step explanation:

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25  <== this is where the error was made.

Step 2: −5x = 53

Step 3: = −5x/−5=53/−5

Step 4: x = −53/5

Right steps:

−5x − 25 = 78

Step 1: −5x − 25 + 25 = 78 + 25

Step 2: −5x = 103

Step 3: −5x/−5 = 103/−5

Step 4: x = 103

Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Use the diagram below, if m∠AEC=41°, find each angle measure

Answers

Answer:

[14] 139

[15] 90

[16] 41

[17] 49

[18] 139

[19] 131

Step-by-step explanation:

[14] Since m ∠ CEB is vertical with m ∠ AED = 139

[15] Knowing that m ∠FBD = 90 degree then m ∠ CEF = 90 degree

[16] Since m ∠ DEB is vertical to m ∠ADC Thus answer = 41

Note: vertical angles are angles opposite each other where two lines cross.

[17] Since m ∠ FED = 90 degree and m ∠ DEB = 41 then 90 - 41 = 49

[18] To Find m ∠CEB we have to subtract from m ∠ DEB

180 - 41 = 139

[19] Knowing that m ∠ FED = 90 degree and m ∠DEB = 41

Then m ∠ AEF =  90 +41=131

write the absolute value equations in the form |x-b|=c (where b is a number and c can be either number or an expression) that have the following solution sets. Two solutions: x=2, x=14.

Answers

Answer:

Write the absolute value equations in the form

x−b

=c (where b is a number and c can be either number or an expression) that have the following solution sets.

Chapter Reference

a

Two solutions: x=2, x=14.

Step-by-step explanation:

The absolute value equations in the form |x-b|=c is 6.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Two solutions are x=2 and x=14

Now,

To write an absolute value equation that has these solutions, we need to find a common value of b and c that satisfy the property above. One possible way to do this is to find the midpoint and the distance between the two solutions. The midpoint is the average of the two solutions, and the distance is half of their difference. The midpoint will be the value of b, and the distance will be the value of c.

Using this method, we get:

b = (2 + 14) / 2 = 8

c = (14 - 2) / 2 = 6

Therefore, by the given equation the answer will be 6

Answers

Answer:

Step-by-step explanation:

Soccer game lasts 2 hours and 15 minutes

The game starts at 11:00 A

The park closes at 6:30

The first thing we need to do is to find when Hamid's soccer game finishes

2 1/4 + 11:00 = 13 1/4 = 1:15

(uh so don't know if this is the correct formula for finding time but the answer is correct)

Guessing that each game lasts 2 hrs and 15 mins, we do the same thing

1.25 + 2.25 = 3.75 = 3 3/4 = 3:45

(i added decimals bc i find it the easiest way for me) 1 game
